Product Description:

The CSH01.1C-PB-EN2-ENS-MA1-S2-S-NN-FW control section belongs to the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. Installed in an IndraDrive modular drive set, it acts as the command layer that translates fieldbus data and local sensor feedback into torque, speed, or position references for the associated power module. By combining field communication, analog measurement, and integrated safety, this unit streamlines axis control tasks encountered in packaging machines, material-handling lines, and other automated equipment.

For plant networking, the module uses PROFIBUS. This interface lets PLCs exchange cyclic setpoints and diagnostic bytes without additional gateways. A maximum bus speed of 12 MBaud is supported, allowing short update times when many drives share the same segment. Local process values can be acquired through a built-in analog channel rated at ±10 V / 160 kohm, which minimizes loading on external transducers. Discrete functions such as limit switches enter through inputs rated at 24 V / 3 mA, while binary states such as drive-ready or fault are returned on outputs that can source 24 V / 0.5 A to drive relays or indicator lamps. These electrical levels match the 24 V control circuitry commonly found in industrial cabinets.

Motion feedback is processed by a primary encoder input that accepts EnDat 2.1 / 1 Vpp / 5 V TTL signals, with auxiliary sensors powered by a secondary supply of 11.6 V / 300 mA for IndraDyn or HIPERFACE devices. Two extension ports provide 12-bit resolution ±10 V inputs and outputs for additional analog loops such as tension or pressure regulation. Functional safety is handled through the integrated Safe Motion package, and its relay-based channel presents a normally open contact rated at 24 V DC / 1 A so external emergency-stop circuits can remove torque without cutting main power. A D-SUB safety connector and a 24 V DC feed line support the drive-integrated protection architecture.
